Move over thigh gap - looks like the bikini bridge is the next thinspiration, thanks to a prank campaign.

Circulated by users anonymous message boards (4chan/b/) in particular, the explosion of unhealthy body bridge images across the web earlier this week is creating a dangerous buzz, feeding those starving for approval and upping competition in the online hunger games. The body bridge features a super flat stomach flanked by jutting hip bones. When lying down, this creates a space between your bikini bottom and concave stomach.

What started as a hoax is providing endless unhealthy selfie possibilities and experts are worried about impressionable young women starving themselves for the coveted caved-in look, ramping up eating disorders and online fat-shaming. This newest benchmark for beauty is ugly– it encourages young women to develop poor body images and batters their self esteem, report experts.

Last year it was the deplorable thigh gap that was deified, a Tumblr darling, glorified and glamourized on social media, cycling through pro-eating disorder blogs and thinspo hashtags. Twitter and Facebook accounts were dedicated to thighs that don’t meet at the top. Flat is where it’s at this time around. “It’s the ultimate beach accessory,” states a Buzzfeed article entitled 12 Perks of Having a Bikini Bridge, which has since been removed. Sites surging with bikini bridge images, along with clicks and tweets are growing this unhealthy and unrealistic beast.

“Here we go again! Another body anomaly that is mostly shaped through genetics. As if photoshop hasn’t done enough to harm girl’s self image, now they want a hollow stomach?” says New York psychologist Dr. Wendy Walsh.

“This is yet another disturbing trend that is set to go viral with Internet selfies. When are girls going to Instagram and Snapchat their real power part: Their GPA?” adds Walsh.

“This bikini bridge may become the bridge to disappointment. Girls do not need any more mirages to chase on the road to body satisfaction and positive self worth," says Dr. Robyn Silverman.
